【Abstract】 A method of evaluating the stress intensity factors of the concrete structures under the seismic loading is presented. The method is based on the response spectrum method. The modal stresses intensity factors are calculated by the energy principle. Then by modal superposition, the total stress intensity factor can be obtained.更多还原
